c++ - SQLExecute always returning "[Microsoft][SQL Server Native Client 10.0]String data, right truncation" in parameters more than 8k sized -

-

when execute sqlexecute function returns me "[microsoft][sql server native client 10.0]string data, right truncation" when parameter has more 8k bytes. paste code below. i'm trying do: store xml file in column declared varbinary(max) through stored procedure via odbc drivers (visual c++ 2008) in sql server 2008 r2. sp converts varchar varbinary calling set @xml_file_bin = convert(varbinary(max), @xml_file) works fine if try pasting whole xml int sql server management studio. think wrong binding in sqlbindparameter. code:

char* cxmlbuf; contains buffer retcode = sqlbindparameter(     hstmt,              //statementhandle     1,                  //parameternumber     sql_param_input,    //inputoutputtype     sql_c_char,         //valuetype     sql_char,           //parametertype     sql_desc_length,    //columnsize     0,                  //decimaldigits     cxmlbuf,            //parametervalueptr     buflenght,          //bufferlength     &cbxml              //strlen_or_indptr );  if (retcode != sql_success && retcode != sql_success_with_info)     return;  sword id = 0; sqlinteger cbid = 0; retcode = sqlbindparameter(hstmt, 2, sql_param_output, sql_c_sshort, sql_integer, 0, 0, &id, 0, &cbid);  if (retcode != sql_success && retcode != sql_success_with_info)     return;  retcode = sqlprepare(hstmt, (sqlchar*)"{call my_store_proc(?, ?)}", sql_nts);  if (retcode != sql_success && retcode != sql_success_with_info)     return;  retcode = sqlfreestmt(hstmt, sql_close); // clear cursor state retcode = sqlexecute(hstmt); //in part retcode -1 , "[microsoft][sql server native client      //10.0]string data, right truncation" returned if xml buffer //has more 8k

found it! i've declared sqlinteger cbxml = sql_nts; instead sqllen cbxml = 0; thanks.
